MEAT CHOPPER.

Application 'filed October 28, 1918. Serial no. 259,907.

To all to hem it m my "concern Be it known that 1, AUGUST F. BAUER, a citizen of the United States, residing at Kansas City, in the county of Jacksonand State of li lissouri, have invented a certain new and useful improvement in Meat Choppers, of which the following is a specification. 1

My invention relates to improvements in meat choppers.

It relates particularly to the type of power choppers in which a screw is rotatable in a cylinder carrying at its dischargeend a perforated plate through which'the material to be chopped forced by a knife rotatably' mounted at the forward end of the feed screw.

One of the objects of my invention is to provide a support for the forward end of the feed screw which can be lubricated without liability of the lubricating material mixing with the chopped material.

Afurther object of my invention is to -provide a support for the forward end of the feed screw whichwill be subjected to aminimum of wear, and by'which the-knife will be retained in proper operative relationship to the perforated. plate,and which will eliminate the usual chattering of the forward end of thefeed screw due to the wearing of an unlubricated bearing, government restrictions preventing the lubrication of bearings where the lubricating material is liable to mix with the chopped material.

My invention provides further other novel features which are hereinafter full-y described and claimed.

In the accompanying drawing which illus trates the preferred embodiment of my invention,

Fig. 1 is a side elevation of a meat chopper provided with my improvement.

Fig. 2 is an enlarged horizontal sectional view of the forward portionof thechopper.

Fig. 3 is a cross section on the line 3-3 of Fig. 2.

Fig. 4 is a cross section on the line 4-4- of Fig. 2.

Similar reference characters designate similar parts in the different views.

1 designates the column or base of the chopper, 2 the cylinder, and 3 the feed screw, which is of the usual type, and which is provided inits forward end with an axial screw threaded hole in which is fitted the inner end of a forwardly extending horizontal axial shaft 1 having a squared portion 5 on which is removably fitted the usual knife 6.

The outer end of the cylinder 2 is screw threaded andhas secured thereto a member 7, preferably a transversely divided internally screw threaded clamping ring 8 arranged to hold a perforated plate 9 against the outer 'side of the knife 6. A washer 10 may be inserted between the knife 6 and the screw 3 on the shaft 4:.

The ring 8 is preferably provided with two peripheral lugs 11 and 12, the latter having a threaded hole inv which is fitted a screw 13 which is rotatably mounted in the lug 11. By adjusting the screw 13, the ring 8 may be tightly clamped on the cylinder 2.

The ring 8 is provided with one or more forwardly extending arms 14 which are integral at their forward ends with a circular threaded portion. 15'on which is fitted a screwthreaded cap 16,, which is adapted to press grease againstthe outer end of a hearing carried within the circular portion 15 and in which the outer end of the shaft 4 is rotatably mounted. This bearing comprises, preferably two rings 17 and 18 mounted concentrically one within the other. The ring 17 is provided with two annular peripheral grooves in which are located balls 19 which are alsoloc-ated in two grooves provided on the inner side of the outer bearing ring 18. The inner'ring 17 encirclesthe shaft 4-.

At the inner end of the bearing just described, a sealing means is provided for preventing grease or oil passing inwardly from the bearing on the shaft 4:. Such sealing means consists, preferably, in a ring 20 of the same diameter as the ring 18, mounted on the shaft i in the circular portion 15, and provided 'on its inner side with an annular groove in which is fitted packing material 21, such-as feltor waste.

The shaft 4: extends through and is rotatable in a central hole provided. in the perforated. plate 9.

Grease is placed in the cap 16, and'the latter is screwed-.ontothe circular portion 15, so as to force the grease into the bearing and around the outer end of the shaft 4. The ring 20 and packing material 21 prevents the grease from passing along the shaft 4 to a point where the grease could mix with the chopped material passing outwardly through the perforated plate 9. The shaft 4 supports the outer end of the screw 3.

By removing the ring 8, after loosening the screw l3, the plate 9, knife (5, shaft st and feed screw 3 may be removed for the purpose of cleansing.

My invention provides a lubricated support for the outer end of the feed screw with out liability of the lubricating material mix ing with the chopped material, said support being located forward of and spaced apart from the point of discharge of the material, such point being, as shown, at the forward side of the perforated plate 9.

I do not limit my invention to the sti: ture shown and described, as modifications, within the scope of the appended claims, may be made without departing from the spirit of my invention.

What I claim is:-

1. In a meat chopper, a. chopper cylinder, feed .screw rotatable therein, perforated plate mounted transversely across the discharge end of said cylinder, the chopped ma terial being discharged from the chopper at a Joint forward of said plate, a hearing member secured to the cylinder and having an arm extending forwardly beyond the discharge end of the cylinder, said member having means for retaining said perforated plate in operative position, an axial shaft extending through said perforated plate and having its inner end secured to and rotatable with the outer end of said screw, the outer end of the shaft being rotatably mounted in said bearing member at a point forward of and spaced apart from said point of discharge, and a knife mounted on and rotatable with said shaft intermediate the screw and said perforated plate and having a bearing against the inner side of the latter, substantially as set forth.

2. In a meat chopper, a chopper cylinder, a feed screw rotatable therein, a perforated plate mountedtransversely across the discharge end of said cylinder, the chopped material being discharged from the chopper at a point forward of said plate, an axial. shaft extending through said perforated plate and having its inner end secured to and rotatable with the outer end of said screw, a knife mounted on and rotatable with said shaft intermediate the screw and said perforated plate and having abearing against the inner side of the latter, and means carried by said cylinder for retaining said perforated plate in operative position and for rotatably supporting said shaft at a point forward of and spaced apart from said point of discharge, substantially as set forth,

3. In a meat chopper, a chopper cylinder. a feed screw rotatable therein, a perforated plate mounted transversely across the discharge end of said cylinder, the chopped material being discharged from the chopper at a point forward of said plate, an axial shaft extending through said perforated plate and having its inner end secured to and rotatable with said screw, a knife mounted on and rotatable with said shaft and bearing against said perforated plate, and means carried by said cylinder for retaining said perforated plate in operative position and for rotatably si'ipporting the outer end of said shaft at a point forward of and spaced apart from said point of discharge, substantially as set forth.

4-. in a meat chopper, a chopper cylinder, having a threaded discharge end, a feed screw rotatable therein, a perforated plate mounted transversely across the discharge end of said cylinder, a shaft extending through said perforated plate and having its inner end secured axially to and rotatable with said screw, a knife mounted on said shaft intermediate the screw and plate and bearing against the latter, a trmisvcrsely divided threaded ring member fitted on the threaded end of said cylinder and engaging and retaining said plate in its operative position, and adjustable means for contracting said ring member, so that it will clamp said cylinder, substantially as set forth.
